High speed electronic data transmission system

Abstract

A high-speed electrical data transmission system ( 10 ) includes a signal mixer ( 13 ) for receiving high-speed data from external network transceiver ( 12 ). The signal mixer ( 13 ) converts the data into an electrical current-fluctuating data signal. A signal processor ( 17 ) is located remotely of the signal mixer ( 13 ) and is connected electrically thereto by a simple/inexpensive cable ( 15 ) having only two operative conductors and receives the current-fluctuating data signal via the cable ( 15 ). The signal processor ( 17 ) converts the current-fluctuating data signal into a voltage-fluctuating data signal for distribution to a local area network.

1. A high-speed electrical data transmission system, comprising:
 a first signal mixer for receiving high-speed data and comprising means for converting said data into a first electrical current-fluctuating data signal; 
 a first signal processor located remotely of the first signal mixer and connected electrically thereto for receiving the first current-fluctuating data signal and comprising means for converting the first current-fluctuating data signal into a first voltage-fluctuating data signal; 
 a transceiver located between the first signal mixer and a first external network, the transceiver communicating said high speed data to the first signal mixer; 
 a second signal processor providing a second voltage-fluctuating data signal to the transceiver; 
 the first signal processor being connected electrically to a second network of one or more appliances to communicate said first voltage-fluctuating data signal thereto; and wherein the system further comprises: 
 a second signal mixer at said remote location providing a second current-fluctuating data signal and being connected electrically with said second signal processor, the second signal processor converting the second current-fluctuating data signal into said second voltage-fluctuating data signal presented to the transceiver. 
 
     
     
       2. The system of  claim 1 , comprising a cable comprising only two operative conductors connected between the first signal mixer and the first signal processor for carrying said first current-fluctuating data signal. 
     
     
       3. The system of  claim 1 , wherein the transceiver is a fibre-optic transceiver and wherein the external network is a fibre-optic network.
